摘要： An external circulation type ball thread device includes a threaded shaft having a ball thread groove in the outer surface; a ball nut having a ball thread groove in the inner surface; and a number of balls fitted between those ball thread grooves, the balls being circulated while being led in a ball circulating tube which is secured to the outer surface of the ball nut with a tube retaining member. In the device, the ball nut has in the outer surface a tube supporting groove which is formed along the ball circulating tube which is arranged inclined with respect to the axis of the threaded shaft, to support the bottom of the ball circulating tube, and an annular groove which is formed across the tube supporting groove; and the tube retaining member is made of an elastic thin plate in such a manner that the tube retaining member is substantially C-shaped in section so as to be fitted in the annular groove, and has an engaging groove which is engaged with the ball circulating tube. Thus, the device is simple in structure and high in productivity.

摘要： A preliminary thrusting mechanism for a screw device serves to achieve not only constant position type preliminary thrusting but also constant pressure type preliminary thrusting. The preliminary thrusting mechanism includes as essential components a screw shaft having a spirally extending screw groove formed axially along the outer surface thereof, a first nut threadably engaged with the screw shaft, a second nut operatively connected to the first nut in series and threadably engaged with the screw shaft, a rotation stopping unit for preventing the second nut from being rotated relative to the first nut, a thrusting unit including a thrusting member adapted to impart to the first nut and the second nut a certain intensity of thrusting power effective in the opposite direction for allowing them to be displaced away from each other in the axial direction, and a stopping unit for preventing the thrusting member from being displaced further when the thrusting member is displaced by a predetermined distance. In practice, the thrusting unit includes a liquid pressure source, a liquid pressure supplying path and a pressure chamber, and the stopping unit includes flanges each serving to prevent further displacement of the thrusting member.

摘要： A ball screw apparatus is provided with a screw shaft having a spiral ball screw groove, a nut member having a screw groove, and a plurality of balls. A smoothly continuous worked portion is formed at a portion of the screw groove by grinding a corner portion between the screw groove and a connecting way. The worked portion is formed such that the distance between the screw grooves is gradually reduced regarding an advancing direction of the ball entering from the connecting way in between the screw grooves. This worked portion extends from an end of the connecting way in a circumferential direction of the nut member and within a range of 90° from the corner portion along the circumferential direction of the nut member.

摘要： A ball screw apparatus comprises a screw shaft, a nut, and a plurality of balls. A first helical groove is formed at an outer peripheral surface of the screw shaft. A second helical groove is formed at an inner peripheral surface of the nut. A rolling contact way of balls is defined by the first helical groove and the second helical groove facing each other. A connecting way formed of a tube for connecting a part and another part of the rolling contact way is provided on the nut. An endlessly communicating circuit is defined by the connecting way and the rolling contact way. Each of the balls is endlessly arranged in the circuit. A smoothly continuous machined portion is formed by cutting out an angular portion between the helical groove and the connecting way of the nut.
